3060L is located inside the enclosure and can be accessed by sliding
the top cover of the enclosure to the rear.

Internal Backplane

An integrated backplane separates the front and rear sections of the chassis. This
circuit board provides logic level signals and low voltage power paths. Thermal
sensors and I
PSU/cooling module operating status. This board contains no user-serviceable
components.
WARNING
Accessing the backplane board may lead to fatal damage of the system. Also,
